Proper Use

药物信息提供方:IBM Micromedex

It is very important that you use this medicine exactly as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. To do so may cause unwanted side effects.

This medicine is to be used only in the vagina. This combination medicine is contained in a ring that is placed into your vagina. The ring will slowly release small amounts of the medicine for your body to absorb.

This medicine comes with a patient information leaflet. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

NuvaRing® is used in a 4 week cycle. You may start using the vaginal ring on the first day of your menstrual period or between the second and fifth day, keeping it in place for 3 weeks.

Once the ring is in place inside your vagina, you should not be able to feel it. If you feel uncomfortable, the ring may not be inserted far enough. Gently push the ring farther into your vagina. If you feel pain, talk to your doctor.

Check for the presence of the ring inside your vagina regularly (including before and after having sex).

The ring may move down into the lower part of your vagina accidently. This can happen if you strain to have a bowel movement. Use your finger to gently push the ring back into place. If the ring comes all the way out of your vagina, rinse it off with warm water and put it back in. Call your doctor if the ring comes out several times.

Remove the vaginal ring after 3 weeks on the same day of the week and time it was inserted. During the 1-week break, you will usually have your menstrual period. Another ring will be inserted after a week.

While using this medicine, you may need to use an additional form of birth control method (eg, condom, spermicide) during the first 7 days to prevent pregnancy. Do not use a vaginal diaphragm because the ring may affect how the diaphragm fits.

If you need to remove the ring, hook your finger through it and pull it out.

If you are switching from a combination hormonal method (eg, pills, patch) to NuvaRing®, start using this medicine on any day. Do not start using this medicine any later than the day you would start your next birth control pill or patch.

If you are switching from a progestin-only method (eg, progestin-only pill, implant, injection, intrauterine system) to NuvaRing®, start using it on the day after you used your last progestin-only pill, or on the day your implant or IUD is removed, or on the day you would have your next injection. You must also use an additional barrier method of birth control (eg, male condom with spermicide) for the first 7 days.

Do not eat grapefruit or drink grapefruit juice while you are using this medicine. Grapefruit and grapefruit juice may change the amount of this medicine that is absorbed in the body.


The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Missed Dose

Call your doctor or pharmacist for instructions.

If NuvaRing® has slipped out of the vagina and it has been out less than 3 hours, you should still be protected from pregnancy. If NuvaRing® has been out of the vagina for more than 3 hours, you may not be adequately protected from pregnancy, and must use an extra method of birth control until NuvaRing® has been in place for 7 days in a row.
